Chapter 10 Construction Management 建设管理部门10.1 the procurement and implementation of structural steel for buidings begins with the owner`s decision to use steel as the primary structural system for the building采购和实现的钢结构的建筑开始与业主的决定使用钢作为主要结构系统的构建this decision is generally made early in the design process in conjunction with the architect and structural engineer for the project10.1 这个决定通常是在设计过程中尽早做出会同建筑师和结构工程师的项目the construction manager or design-build firm advises the owner on material availability设计、建设施工经理或公司建议业主在材料的可用性costs, suitability 成本、适用性and scheduling aspects of the structural frame types和调度方面的结构性框架类型in many cases 在许多情况下the construction manager or design-build firm consults with steel fabricators for preliminary pricing设计、建设施工经理或公司担任钢铁制造商为初步定价scheduling, and layout information that is used in deciding which structural system to utilize调度和布局信息,用于决定哪些结构系统利用Structural Design 结构设计Once the decision is made to use a structural steel frame, the architect and structural engineer proceed with structural design layouts for the building.一旦决定使用一个钢结构框架,建筑师和结构工程师进行结构设计布局的建筑。
Contract Documents合同文件Upon completion of the schematic design studies, the architect and structural engineer proceed with design development and contract documents of the structural engineer is primarily responsible for engineering of the structural steel frame and development of the detailed structural contract documents. The structural documents include foundation plans and details, structural notes, and design loads, column schedules , schedules details, structural notes ,and design loads, as well as the structural specification.在完成方案设计研究,建筑师和结构工程师进行设计开发和合同文件的结构工程师主要负责工程的钢结构框架和开发的详细结构合同文件。
结构文档包括基金会计划和细节,结构性票据,和设计荷载,列时间表,日程安排的细节,结构性票据,和设计荷载,以及结构规范。
Bidding n. 投标；出价；命令After completion of the contract documents, the owner and architect prepare the bidding documents, bidding documents are used together with contract documents to obtain bids from contractors for the construction of the building. The owner and architect solicit bids from qualified contractors, using these documents, Bids for structural steel maybe in the from of subcontract prices, which are included in the general contractor`s lump sum proposal , or the owner may divide the project into separate prime contracts with the steel contractor bidding directly to the owner . When the owner employs a construction manager or design-build firm , the construction entity usually takes lead role in preparing the bidding documents and managing the bidding process for the owner.建成后的合同文件的所有者和架构师准备投标文件、招标文件一起使用与合同文件获得从承包商投标建造的建筑。
业主和建筑师恳求的竞标合格的承包商,使用这些文档,竞购钢结构也许在从分包合同的价格,这是包含在总承包的一次性的建议,或者拥有者可以将这个项目划分成单独的黄金合约与钢承包商投标直接向老板。
当老板雇佣了一个施工经理或公司设计、建设、施工单位通常需要领导角色在准备招标文件和管理竞标过程的所有者。
During the bidding process, the general contractor defines thesubcontract workscopes and solicits subcontract prices from steel fabricator, erectors, and specialty contractors. The general contractor may wish to subcontract the complete structural steel package to a single steel subcontractor, or may choose to divide the steel portion of the project into multiple subcontracts. In the case of a single subcontract, the general contractor will identify a qualified steel fabricator or erector to obtain a bid for the complete structural steel package.在竞标过程中,定义了workscopes总承包商和分包合同分包合同征求价格从钢铁制造者,基层网点建设者,和专业承包商。
总承包商可能希望分包完整的钢结构包到一个钢分包商,或者可以选择把钢的部分项目分成多个分包合同。
对于一个分包合同,总承包商将确定一个合格的钢铁制造者或安装工来获取一个竞购完整的钢结构方案。
The steel contractor (fabricator or erector) will solicit lower tier subcontract prices for the various portions of the steel package. Typically the fabricator, (who is not also an erector) would seek lower tier subcontract prices for steel erection, metal deck supply and installation, and shear studs, as well as other specialized aspects of the steel portion of the project .The steel contractor may also be charged by the general contractor with furnishing the miscellaneous fabricated steel items used throughout the project . Examples of these items are loose lintels, plates, and bolts installed by the mason, or steel pipe railings and metal stairs. If these items are to be included in the steel contractor`s subcontract, thegeneral contractor should specifically include these in the subcontract workscope.钢铁承包商(制造者或安装工)将征求分包价格较低的层的各个部分钢包。
典型的制作者,(没有一个安装工)将寻求降低分包钢材的价格线安装、金属甲板供应和安装和抗剪螺栓,以及其他专业方面的钢的部分项目。
钢铁承包商也可能被起诉的总承包商与家具的杂项装配式钢在整个项目中使用的物品。
这些项目的例子是松散的门楣,盘子,螺栓安装的梅森,或钢管栏杆和金属楼梯。
